"The new guitar both awesome and annoying. The fret buttons are the exact same thing as the GH3 guitar, so nothing big there. A slider bar has been added for solo sections, which is pretty cool actually. I'm not a bit fan of the lower buttons on the Rock Band guitar, but these actually work out pretty well. The biggest change and what makes me happy everytime I play is a dedicated Star Power activation button that sits right under your palm."
